Topic: B-Eleven sha-256 ASIC miner - page 6. (Read 14775 times)

Very intersting is there anything that tells efficiency?  I was thinking on miner they listed multiple speeds.  So I'm really curious what they do with this miner.

Really want to know efficiency to.

chrome translation I see chips will be in near Christmas or New Years

If true gear will be at least 1 month after that.  Lets say on my birthday Jan 27th.

So it is a waiting game for now.

Wow, that's awesome!  So actually on schedule, and we may very well see the 14 nm by January 2016. 

Some news about B-alaven chips (please use some translation service). https://forum.bits.media/index.php?/topic/9440-allrossiia-new-b-eleven-10ths-antminer-s7/page-7#entry335679

On their Hash Investment page in the FAQ is this Question.


With this Answer.


I think there is more than one way the answer could be interpreted, however I interpret it as being they are using Samsung?

 Actually, the chip specs are competitive with the BM1385 in the Bitmain Antminer S7 on efficiency, and a hair better than the Avalon 6 chips.
 Nowhere near "too good to be true".

 $500 per TH would be MORE than Bitmain has been charging for the S7 by quite a bit, and somewhat more than for the Avalon 6.
 Not even in the BALLPARK of "too good to be true".


 BW.COM is part-owned by Lketc, of Dragon Miner fame - tends to lend legitimacy to the probability of the B-Eleven being a real unit fairly soon, per their announcements.

 It seems that the chip involved will be a non-custom 14nm design - leaving room for another generation of improvement and giving some EXPERIANCE at that process node, which might give the chipmaker a small head-start on the 14nm Full Custom generation over Bitmain (and WILL put them well ahead of Avalon given commentary out of those folks).

 There is still some question as to who is actually designing the chip - Lketc has a history of using Innosilicon chips in their miners, and Innosilicon let slip that their A3 14nm chip had been taped out some months back.


 I'd rate the probability of "fake" as pretty close to zero in this case, the only real questions in my mind about it are "when will it go on sale", "how much",  "what will be the exact details for TH and power usage", and "what sizes will it be available in".

0.26 J/GH @ $0.50/GH is too good to be true?

It is proven, that these kind of efficiency could be allready achieved based on 28nm ASICs, so it doesn't seem to be an outstanding 14nm design.
And why should one pay a higher price per GH as for a comparable 28nm miner?

 51ASIC.ru looks like a scam to me. However the miner is backed by BW.com / LK Group Limited and CHBTC. I would expect the Miner to be real, although they are still only showing renderings. They announced  0.87 BTC/TH so for the 3TH Miner that is 2.61 BTC for bulk orders. Individual prices have not been announced, also the exchange rate has moved a lot since then so would expect this price to change.

Have heard that so many times. Even I have done with a number of places who started up promised to send equipment to test and never sent anything out. Am guessing are still awaiting to have a test unit sent out. Even when a unit comes can just send a unit out and get a review done on it and then still never send equipment out to customers. But will be interesting to see if really get sent a unit out to review. How long as it been since you where told you will have one sent out and any comments or response on them sending out?

That reseller (51asic.ru) promised to provide one to me for testing and review once it will appear.  

Sounds too good to be true with the power used. Also the people who made the threads in the quote ahve made maybe 1 or 2 posts and never been seen again. $500 per TH seems to be under cutting a lot of the other mines too. 14nm Technology used to lol id be surprised if this is really being used or actually made the equipment.

Each chip is capable of producing 34.6-63 GH/s, with a power consumption of 18 W based on a voltage range of 0.59-0.76 V. I will only believe such findings if theirs a unit being shown in real time and am around to see it live that it works or some company like bitmain or avalon pick it up or some company that people are buying from and not scam.

Sounds to good to be true more than likely is fake.

No nothing more. I emailed them the other day asking if there were any updates and in reply they pointed me at Sina microblogging  but could not find anything there.

Rich

Any update on the B-Eleven?

S1 is 55nm but I take your point. Could also be the value of Full Custom showing in the BM1385 ASIC?


Rich

I have just crunched some numbers from the available data on B-Eleven. Several assumptions made, so plenty of room for error.

Data from Bitcoin Magazine

ASIC 34.6 to 63GH/s
Core Voltage 0.59V to 0.76V
Power Consumption 18W


So if we assume that 18W is at 63GH/s (If 18W refers to a Lower GH then numbers are worse?

Then to get 3TH we need 48 Chips and consumption would be 18W x 48 = 864W = 0.28J/GH

If we add something for the Controller & Fan(s) thet might become 880W = 0.29J/GH

Now if we loose another 5% in the PSU that becomes 0.3J/GH

The other data we have accompanies the sketches, 260W/TH (We are not told if this is at the wall?)

Which would give 780W for 3TH which is 0.26J/GH

So take your pick, but these numbers are in the same league / slightly worse than an S7, would you not expect something better from a 14nm Chip?

However it's all about price & delivery date, we will see. 


Rich

.87 B per TH sounds more likely than .87 B per miner - but it would still be better pricing by quite a bit vs. the S7 and would be in the ballpark of having a prayer of RoI with cheap enough electric.

(does a quick visit to bitcoinwisdom)

 Hmmm, using my current "standard assumptions" this thing will barely achieve RoI (NOT including cost of PS or shipping) at my current 6.7 cent "incremental" electric rate, *IF* it goes on sale to the public at 0.87/TH soon enough to get delivered by 1 December 2015 and if the halfing does not happen before mid-July.

 TONS better than the S7 manages at it's current pricing, but still a bit marginal at best for most folks.

They have already stated that later in the Year they will open up individual sales.
But there is no way these will be 0.87BTC ($235) for 3TH So I will stick with this being a /TH price. This is supported by the current B-Eleven Hash Investment being sold at 0.76BTC/TH

Some GB's do make a lot of sense like look at U3 or something.  Order of 20... group buy or re-seller is who are buying that.

I would not pre-order gear in this case (or almost any case).  I mean not even a working prototype shown just renderings.  To many stop at rendering stages with money.

I predict after release the number is dropped as they will have already gotten big buyers set up on gear from big pre-order numbers.  And it still could be a number that needs a group buy.  But I dont see the 333 number sticking forever.

Group buys carry some risk. Pre-orders carry risk. Put the two together, and the probability of failure just goes too high for me. I been in a couple and the best outcome was a small profit, only because we were able to sell the hardware to somebody else at a profit.

They do mention that is for pre-orders.   So they could hope to get big customers on pre-order.   Since 333 units is more of a data center order.

I'm hoping once it's truly out they lower the amount to order.  Guess we will wait and see.
